The Best Garage Door Insulation Kit
Good: Matador Garage Door Insulation Kit Foam R-4.8 Value
The Matador kits come in two different sizes: Large and Extra Large. The total R-value of these kits is 4.8 with the 1 1/4″ thick panels.
The large kit is made for doors 7 feet tall and the extra large kit is for doors 8 feet tall. Both kits fit up to 9 foot wide doors. If you have a rather large door you may need to purchase an extra kit. Make sure you measure your garage door before ordering.
The only tool you will need for installation is a utility knife to trim the panels.
Better: Owens Corning Garage Door Insulation Kit R-8 Value
With an R-value of 8, this kit is a better choice than the Matador. It is made of fiberglass with a white vinyl side for stylish looks. You will need a utility knife and tape measure to install this insulation kit.
This kit will fit doors up to 9 feet wide and has a cleanable surface.

What to Consider Before Choosing Garage Door Insulation
The 3 types of insulation:
- Reflective Foil
- Polystyrene foam
- Foam DIY Kit
The reflective foil insulation is sold in rolls and is around an inch thick. It works by creating an air pocket and has an R6 insulation value. It needs some sort of adhesive to be installed on the garage door and is one of the cheaper options. It can be ugly in my opinion as seen in the photo below.
Polystyrene foam is sold in large sheets and will have to be cut to fit the garage door panels. It is a bit more work to cut and install but has a better R-value than the reflective foam.
Foam DIY Kit
The final option is the garage door insulation kits which are usually made of foam and have a better R-value. These kits have pre-cut foam sheets which fit into each of the door panels. The foam sheets may need to be trimmed depending on the size of the garage door. Installation can take as little as an hour to complete.
Other Things to Consider
The extra weight of the insulation may affect the balance of your garage door. You may need to have the springs adjusted yourself or by a garage door technician.
You should also look at the R-value of the insulation kits. The higher the R-value the better the insulation. Ideally, you want to get the best R-value possible for your garage door.
You should inspect the rubber seals around your garage door. Make sure there are no holes or breaks which will let drafts in. Replace any broken or missing seals.
